The heiress took to her Twitter Tuesday to express outrage over an alleged burglary that apparently took place today at sister Nicky Hilton Rothschild's house in Los Angeles.

"The cops finally just got to Nicky's house," Paris, whose own home was ransacked a year ago by an alleged bunch of burglars that targeted celebrities, wrote shortly after 4 p.m.

"She thought her cats escaped in the robbery but she just found them under the bed. Thank God."

Beforehand, the LAPD could not confirm whether a car had been dispatched to Nicky's house—and we know why.

Paris tweeted the following at 3:15 p.m.: "It's unbelievable how my sister called the cops over an hour ago and they still haven't shown up. Her house just got robbed, so messed up :("

Nicky Hilton's rep couldn't immediately be reached for comment. But for now, Paris has provided enough reaction for everyone.

"I HATE people who steal!" she also wrote. "It's so wrong! I hope they catch whoever did this! There has been so many robberies lately. So scary! :( "

Meanwhile, the the three suspects allegedly responsible for breaking into her house and stealing $2 million worth of jewelry (most of which has been returned) have pleaded not guilty to felony residential burglary.
